Greater Than 
by ch3cknull @ch3cknull
In This Challenge, You should implement a type `GreaterThan` like `T > U`
Negative numbers do not need to be considered.
For example
```ts
GreaterThan<2, 1> //should be true
GreaterThan<1, 1> //should be false
GreaterThan<10, 100> //should be false
GreaterThan<111, 11> //should be true
```
Good Luck!
